ISIDOR SIMOVITZ, OF NEW YORK, N. Y.

FLUSI-IING DEVICE.

To all whom t may concern Be it known that I, IsIDoR SIMovrrz, a

.citizen of .the United States, and a resident of the city of New York, borough of Bronx, in the county of Bronx and State of New York, have invented a new and Improved Flushing Device, of which the following is "valve'is' eliminated and a siphon is substituted. f

Another object View the pro-vision of a iushing device provided with an ordinary valve structure and means for automatically shutting the same 0H when the tank has been filled, and a siphon positioned to .be operated as soon as the valve has been opened.

A still further object of the invention is to provide a flushing devlce with an ordinary inlet valvejand an arrangement of operating mechanism which will comparatively disco neet the float from Athe valve until the tank has 'been emptied.

In the accompanying drawings:

Figure 1 is a longitudinal vertical section through part of a tank and flushing device disclosing an embodiment of the invention.

Fig. 2 is a top plan View of the structure shown in Fig.

Fig. 3 is a view similar to Fig. 1, but showing the parts in the position assumed when the operating cord .has been pulled.

Fig. 4 is a view similar to Fig. 3, but showing the parts in the position assumed when the tank has been emptied.

Referring to the accompanying drawings by numerals 1 indicates a tank of any de-. sircd kind provided with an opening having a fitting 2 of any usual preferred construction, said fitting being designed to receive the lower end ofthe siphon 3, which lower end may be held in place by being beveled and forced tightly in position in connection with some packing 4, or `may be held in position by having the parts threaded and'screwed into place. The Siphon 3 may be made Aof any suitable material andv substantially 1n any 'desired way, but arranged with an up-passageway 5,.,a vtrans- Specification of Letters Patent.

opening 8 so as to break the Siphon when the tank is substantially emptied. It will be noted that by using the siphon 3 no outlet valve is necessary andthe water ismaintamed properly in tank 1 either with` the i 11 of usual construction is provided having a plunger 12 formed with an opening 13 into which the arm 14 projects. A` set screw 15 is provided in the end 0f the casing of valve 11 so 'as to limit the movement of the 'plunger 12 and arm 14 to any desired eX,-

The water from valve 11 passes through the dis` tent, as for instance to take up wear.

charge member 16 into the pipe 17 and from thence through the pipe 18 to a point-near the opening 8. Preferably theend of pipe 18 is bent and also preferably slightly tapered so that the water will project directly into the opening 8 and from thence vup the upleg or passageway 5 so as to quickly start the action of the siphon. After the siphon has been started in this manner, or by rais-l ing the water level in the tank it will continue to operate until the Siphon is broken by air entering one of the openings 9j If pipes 17 and 18 were omitted the siphon '3 would operate but it would be necessary for the level of the water in the tank to move upward by water iiowingthrou'gh valve 11 into the tank. This would occupy a short time, as for instance a few seconds, and, in

order to eliminate .this slow response pipes 17 andA 18 are utilized for causing a subl stantially instantaneous response when the operating cordv19 is pulled. lVhen this cordis pulled lever 20 is moved on its pivotal support 21 which support .entends through the lug 22 of the plate 23. con`v nection with plates 23 it will be observed that the sinne is provided with lugs2 4 and 25 for acc rnmodating certain screws or fastening 1n ,-.ns for clamping the valvefgll in position, calate 23 beingfscrewed or other-v- A wise rigirly secure-d tothetank 1. When the string or cord 1 9 is pulled lever 20 will be operated as just described and the chain 26. pulled so that the pawlor catch 27 will be moved upwardly, as instance to the position shown in Fig. 3, said pawl being pivota'lly mounted at 28on lever 29 rigidly'sesured to the arm 14. Arm 14 is mounted on the casing of valve lland is heldin place by having a pivotal'v (pinBOf pass through suitable lugs 31 exten ing from the casing ofvalve 11. A fitting 32 is pivotally mounted at 33 on the end ting havin an upstanding lug 34 for engaging the en of the pawl 27 for holding the fitting 32 in aliiiement with the lever 29 as shown in Figs. 1 and 4. Fitting 32 carriesl the'rod 35 which has secured to 1t the usual "float 36. When the'pawl 27 is -in operative.

position as shown in Figs. 1 and 4 fitting 32 and rod 35'act merely as elongations of the lever 29 whereby the buoyancy of the iioat 36 will cause the reciprocating valve member 12 to .press tightly against its seat and thereby shut oft' the liow of water from the supply pipe 37. It will be, of course, understood that the tank 1 will be full of water or at least supplied with water to the usual level when the -pawl 27 is disengaged, thleJ water beingv thus supplied whenin the position shown in Fig.1. The disengagement of the pawl 27 will cause the weight of the various parts and the water pressure on -the valve member 12 to move the vlever 29' and associate parts to substantially the positionshown in Fig. 3. 'Phe downward movement of the various parts just described will cause the end of pawl 27 to engage the slanting'side 38 of lug- 34y instead of theA straight face 39. This being the case the w'ater will flow out of the siphon 3 until the tank has been emptied and consequentlythe various vparts have been lowered to the position shown in Fig. 4, whereupon pawl 27 will move over the lug 34 so as to engage the flat surface 39 of lug 34 the ends 'of the plunger or valve member 12 limiting thei movement of lever 29 so as to insure this action. When the parts assume the positionas shown in Fig. 4 the, siphon is broken, thewater continues to enter the tank and as'the tank becomes more and more filled pawll36 will be moved upwardly'until it again assumes the position shown in Fig. 1, whereupon the valve member or plunger 412 will be moved to the closed position for shutting off the water from supplyy pipe 37.

What I claim is: i 1. In a llushing device of the character described, the combination of a tank," a Siphon member arranged in.said tank 'extending through the bottom thereof' so that when it is in operation-'water will flow from the interior ofthe tank tothe exterior until the tank is substantially empty, a supply valve,

' an inlet member fonthe tank, alever structure formed in two-parts lfor normally closing said valve, Said lever having a float on the outer end, a catch for holding the two of lever 29, said iit' nally, manually operated means for disconnecting said catch when itis desired to flush the tank whereby said valve is openedv and maintained` open until the float has been moved downwardly a 'predetermined clistance to'cause the catch to become interpaits of the lever structure in alinement norl said inlet valve for normally acting to hold the same closed, anfarm carrying'a float iv- .otally mounted on theouter end of sai flever, a stop projectin from said arm, a pivotally mounted catc arrangedf'onsaid leally operated'mean's for disconnecting said -vei` and adapted to engage said stop when j .the arm and the lever are in alinement for Alocking the same in alinement, and manucatch whereby the valve lwill open and remain open until the catch hasbeen again closed and the tank refilled.` 3. In a flushing device of the character described the combination of a tank having a discharge structure, an inlet valve for directing water into the tank,l an arm pivotall'y mounted on said valve for actuating the valve plunger therein, an arm pivotally mounted at the outerl end of-said lever, said arm carrying a float, a stop projecting'from said arm, a catch pivotallymounted on said lever formed with an engaging end adapted to engage Vone face of said stop for normally holding said lever and said arm in alinement, and means for disengaging said catch whereby the weight of the parts and the pressure of the water will cause the valve to operiI and thereby move the lever in such a position that4 the catch will engage the stop until the water has been discharged fromthe tank and the float caused to move i i down a predetermined distance.

4. In a flushing device of the character described, the combination with a tank of a discharge member for said tank, a valve in let member for the tank, a jointed controlling structure for ynormally holdingthe valve member against its seat, a catch for maintaining said jointed structure normally in alinement, a iioat arranged on the end of said jointed structure,-and means for manually disengag'ing saidcatch so that only par of the jointed structure will move pivotally a predetermined distance and thereby 'prei vent said catch from again engaging the structure until the tank has been 'substantially emptied.

5. In a flushin' device of the character d escribedthe com Ainat'ion with a tank and a discharge member of a supply valve, a lever structure formed iii two parts for normally closing said valve, said lever having a fioat on the outer end, a catch for holding the two parts of the lever structure in alineinterlocked, and means for :limiting the ment normally, manually operated means swinging movement of that part of the lever for disconnecting said catch when it is decontacting with the valve so that thepart 10 sired to flush the tank whereby the valve 's of the lever carrying the float may come in 5 opened and moved down until the oat has alnement before the float strikes the bot-- been moved downwardly a predetermined tom of the tank. distance to cause the catch to become again ISIDOR SIMOVITZ.
